cdplot() with 'POSIXct' x
Hi,
Given that cdplot() is used to produce the conditional density of a
categorical y along a numerical x, it seems natural that it could be
used with a date or time x (such as 'POSIXct'). Is this desirable? If
so, I've created a patch that would allow this, by coercing the POSIXct
x variable to produce the density, but use the original POSIXct x to
draw the x axis.

ordered logistic regression - cdplot and polr
Hi,
I have a dataset that I am trying to analyze and plot as an ordered logistic
regression (y = ordinal categories 1-3, x = continuous variable with values
3-9).
First is a problem with cdplot:
Produces a beautiful plot, with the "right" trend, but my independent factor
values are transformed. The factor has values from 3-9, but the plot
produces an x-axis with values from 20-140.

Overlay of barchart and xyplot
Hello R Folks,
I am new to R. I have been struggling to overlay a barchart with a
xyplot together on one plot but did not get this worked out. Any help
and idea are greatly appreciated.
I attached R scripts for barchart and xyplot below and also data I used.
What I am trying to do is just to put the barchart and xyplot together
on one plot.

coxme: model simplification using LR-test?
Hi
I'm encountering some problems with coxme
My data:
I'm looking at the survival of animals in an experiment with 3 treatments,
which came from 4 different populations, two of which were infected with a
parasite and two of which were not. I'm interested if infected animals
differe from uninfected ones across treatments.
Factor 1: treatment (3 levels)
Factor 2: infection state

Help with lme Random Factor
Hi,
I need help creating a code for a multiple BACI design (Before-After
Control-Impact) ANOVA. I'm new to R and basically need to run a complex
mixed model ANOVA that treats location as a random factor.
Data are from a fire experiment, run 2001-2004 (2 years pre, 2 years
post). Response is bird abundance. 4 Treatments had 3 replicates each
(forest stands): 1. Control, 2. Prescribed fire

Cumulative Link Models
Dear R community,
I'm trying to analyze a model with an ordinal response variable.
I wonder if clm()s (Cumulative Link Models) are appropriate in my case.
The study compares parasite infestation of porpoises in 1995 and 2009. The degree of infestation is a rank (mild to severe, as ordered factor). In some parasite species clm gives meaningful results. But in one case I started to wonder. In

[off-topic] The better analysis
Hi all,
Firstly excuse-me by this off-topic question.
I'm very confused to decide what is the better analysis to use.
Whem the experiments is a tradicional design of manipulative experiments, it
is easy to decide. But in natural observations is too complicated.
I have 6 farms, each farm cultives some sugarcane's varieties (maybe or not
the same varieties by farm). For each farm I make

Plot binomial regression line
Dear all,
I am quite new with R and I have a problem with plotting a binomial
regression line in a plot.
This is what I type in:

comparative density estimates
I have two series of events over time and I want to construct a graph of the
relative frequency/density of these events that allows their
distributions to
be sensibly compared. The events are the milestones items in my project on
milestones in the history of data visualization [1], and I want to
compare trends
in Europe vs. North America.
I decided to use a graph of two overlaid density

If we go further with this, I'll have to add test cases for lazy mode. I kind

vcpu performance : 1 vcpu for all guets or 4 vpcu ?
Hello all ;)
Tell I have a Xeon server with 4 vcpus
If on this box I have some guets, tell 10, what is the best solutions :
- Set all guests to 1 vcpu ?
- Set all guests to 4 vcpus ?
I well understand that if I set a guest with 4 vcpus and all others only
with one vpcus, then the one with 4 vcpus will have more "cpu time"
available than others guests.
But in case I''d like

ext3 corrupted
Hi there,
For years I've been using the ext3 file system without to think that it can ever gets broken so bad.
This was until last week when a box that I have running Linux from a SanDisk CF went down.
Since then I am struggling with this CF trying to understand what is happening.
The CF is SanDisk ultra II 1GB.
On this I have 4 partitions all of them with ext3:

Samba4, multi-domain Forest and Unix ID mapping
Good day,
I wasn't sure whether this should go to the user list or the
samba-technical list. I chose here based on the descriptions of the list.
Forgive me if my understanding of the naming is inaccurate. It is my
understanding that Samba3 (and I believe 4, as well) has a very powerful
SID<->UID mapping mechanism which will auto create the UID in a range.
This is what I mean by Unix ID

[LLVMdev] Work in progress patch to bug 2606
In thinking about this we could use a Mutex::tryacquire(...) (non-recursive), around JIT::runJITOnFunctionUnlocked(...)'s
while loop, and use your JITEmitter:: getLazyFunctionStub(...) suggestion in place of forceEmitFunctionStub(...). Is the lock
attempt too heavy, even if it is implemented with atomics? I'll implement this when I have time.
